Tree Trunk Patents (Class 43/108)
  • Patent number: 11707024
    Abstract: The main objective of this invention is to improve the efficiency and service life of a rubber tree rain guard seal. The performance of existing rubber tree rain guard seals depends on a fixed mechanical and or chemical attachment of the seal to the tree. These methods of attachment prevent the seal from expanding with the circumferential growth of the tree resulting in premature seal failure and damage to the tree within a year of operation. In this invention the seal is comprised of five components that are not fixed to the tree, allowing the seal to expand along with tree growth. An adjustable outer seal connector regulates the pressure required to establish consistent sealing contact against the tree, thus providing extended service life of the seal assembly. The seal assembly comes apart for easy maintenance.

  • Patent number: 9326458
    Abstract: A device attaches to the trunks of plants and trees to prevent snails from reaching the upper portion of the plant or tree which has leaves and fruit subject to attack from the snails. Embodiments of the device have an inner funnel-shaped sleeve which biases against the tree trunk to provide a sufficiently tight closure to prevent snails from climbing between the trunk and the device. Embodiments of the device have a downward facing surface having a plurality of closely-spaced downwardly facing spike members. These spike members are sufficiently closely spaced so as to substantially or completely prevent snails, including small-sized young snails, from moving across the downwardly facing surface to crawl around the outside of the device to gain access to the upper portion of the tree.

    Abstract: A system for protecting trees and structures from infestation by crawling or climbing insects by attaching an insect barrier to the wall surface of the object to be protected. The barrier consists of a belt means, which may be made from a plastic sheet material and may be wrapped around the object to be protected, including a contact means that engages the surface of the object. The contact means may have a deformable thickness, such as provided by a layer of a non-woven fabric, to prent the passage of insects between the barrier and the surface of the objet. The free ends of the belt means are secured to each other to retain the belt means against the surface of the tree and engage the contact means against the tree surface. The belt means has slippery surface means, having a low coefficient of friction with respect to insects, that prevents the travel of insects on the belt means, preventing them from proceeding over the belt means and infesting the tree or structure to be protected.

    Abstract: A pair of strips formed of dissimilar materials, such as copper and zinc for example, are disposed along a surface to define a zone which inhibits the entry of snails, slugs or the like. The dissimilar materials are ones which exhibit different electrode potentials or voltages when in contact with an electrolyte. It is believed that the exudate or slime present on the skin of a snail or the like has electrolytic characteristics and electrochemical reactions occur when the body of the snail or the like spans the dissimilar strips which reactions are sensed by the snail and discourage further progress. The barrier may be preformed as a flexible, adhesive coated ribbon or tape with the two electrically conductive strips extending along opposite edge regions of one surface of the tape.

  • Patent number: 4400909
    Abstract: A method and device for applying pesticides to growing plants or portions of plants is described in which an area to be protected is enclosed and a small amount of pesticide contained in a packet is placed within the enclosure. The packet protects the pesticide from loss or destruction by water and permits pesticide vapors to escape at a rate sufficient to make the enclosed area untenable to certain pests for an extended period of time.
